Findings from a full review (auth/API, CA and rack channel, config
generation, integrations, UI/agents/scripts), each verified in code:
- rack binary endpoint read any region file via arch=../.. (CA key)
- render endpoint traversal; machine-reported MACs used as file paths
- delegated intermediates could mint admin/rack identities and IPs;
identities now require root-issued certs, intermediates are
ServerAuth-only with both name types constrained
- rack certs were ServerAuth for rack-chosen SANs: now client-only;
racks accept only the region's own cert; join checks the CA
fingerprint; unbound join codes cannot take an existing name; job
results bound to the rack that took them
- rack self-update: region signs binaries with the CA key, the root
unit verifies against the join-time CA in a root-owned dir
- dnsmasq reads a checked, root-owned copy limited to generated options
- commissioning could overwrite deployed machines; MAC takeover of PXE
- injection into dnsmasq/cloud-init/PXE/udev/DNS via names and
machine-reported strings; stored XSS in the UI; CSP and cross-origin
protection; deploy agent shell injection and seed traversal
- Redfish requests confined to the BMC's /redfish/ tree
- admin_http defaults to loopback; body limits and timeouts; secrets
off command lines
Also: IPAM claim/reconcile race, sync stopping on one error, watchdog
race, release wiping the wrong disk, SAN LUNs as auto targets.
